Lawyer for one of two teens charged in connection with the murder of Blair Holt said his client's confession should be thrown out.Attorney Michael Mayfield said the 15-year old suspect told police he did not understand his Miranda rights during initial questioning.

Police said the teen told investigators he handed a gun to an accomplice who tried to shoot a rival gang member. Instead, Holt was shot and died onboard a CTA bus.

The state's attorneys office say it believes the teen was questioned properly.
